The story of the Kyodai Mahjongg 2006 registration code is a bittersweet tale of the "golden age" of shareware and the eventual disappearance of a beloved digital legacy. The Rise of a Masterpiece
In 1997, developer Rene-Gilles Deberdt set out to create the ultimate version of Mahjongg Solitaire after failing to find one that met his standards. The result, Kyodai Mahjongg, became a cult classic, praised for its soothing guitar soundtrack by Miguel Samiez, lush 3D graphics, and deep customisation.
For nearly a decade, Deberdt released frequent updates, culminating in the 2006 version (v21.42). It was distributed as "shareware"—a "try-before-you-buy" model where users could play for free but were encouraged to buy a registration code to remove "nag screens" and support development. The Registration Struggle
While the game remains highly rated by fans on platforms like GOG.com, obtaining a legitimate registration code has become nearly impossible:
Payment Issues: Years after "finishing" the game, the developer restored the ability to buy it. However, due to administrative lapses in sending codes, PayPal closed the account without notice.
The "Nagware" Ghost: Modern players often find themselves stuck with the shareware version. Because the developer no longer updates the game and registration is effectively broken, some users have petitioned for it to be released on platforms like GOG to finally bypass the registration requirements.
A Promise Fulfilled: Despite the registration hurdles, Deberdt maintains that he fulfilled his promise of free lifetime updates for those who bought it between 1997 and 2006. Current Status
